Wastewater after Bioc process has such a kind of characteristic, high organic matters, calcium, magnesium, and salt. Based on long-term lab experimentations, aiming at the characteristics of such water, Keysino designed and developed KS-ZLDP zero liquid discharge system. This system combines wastewater reuse requirements and our company’s engineering experiences using chemical precipitation to remove calcium ions and part of organic matter, and double membrane processing to separate the COD, salt, and water from the wastewater. RO water production can meet cooling water requirement, and RO reject water, through MVR, evaporate and crystallised to achieve zero liquid discharge.

APPLICATION CASE
One pharmaceutical enterprise, wastewater is 6000m³ per day after second clarier, which salt 5000-6000mg/L and COD 500mg/L are around. Using Keysino KS-ZLDP, at least 5250m³/d water can be recycled. Recycled water quality meet the standard of cooling system, organic pollutants and salt turned to solid waste, realizing zero liquid discharge.
